<p id="index-0"><a class="reference external" href="http://www.jython.org/">Jython</a> is an implementation of Python that runs on the Java platform (JVM).
This document will get you up and running with Django on top of Jython.</p>
<div class="section" id="s-installing-jython">
<span id="installing-jython"></span><h2>Installing Jython<a class="headerlink" href="#installing-jython" title="Permalink to this headline">¶</a></h2>
<p>Django works with Jython versions 2.7b2 and higher. See the <a class="reference external" href="http://www.jython.org/">Jython</a> Web site for
download and installation instructions.</p>

<p>If you just want to experiment with Django, skip ahead to the next section;
Django includes a lightweight Web server you can use for testing, so you won&#8217;t
need to set up anything else until you&#8217;re ready to deploy Django in production.</p>
<p>If you want to use Django on a production site, use a Java servlet container,
such as <a class="reference external" href="http://tomcat.apache.org/">Apache Tomcat</a>. Full JavaEE applications servers such as <a class="reference external" href="https://glassfish.java.net/">GlassFish</a>
or <a class="reference external" href="http://www.jboss.org/">JBoss</a> are also OK, if you need the extra features they include.</p>

<span id="installing-django"></span><h2>Installing Django<a class="headerlink" href="#installing-django" title="Permalink to this headline">¶</a></h2>
<p>The next step is to install Django itself. This is exactly the same as
installing Django on standard Python, so see
<a class="reference internal" href="../topics/install.html#removing-old-versions-of-django"><em>Remove any old versions of Django</em></a> and <a class="reference internal" href="../topics/install.html#install-django-code"><em>Install the Django code</em></a> for

<p>The <a class="reference external" href="http://code.google.com/p/django-jython/">django-jython</a> project contains database backends and management commands
for Django/Jython development. Note that the builtin Django backends won&#8217;t work
on top of Jython.</p>
<p>To install it, follow the <a class="reference external" href="https://pythonhosted.org/django-jython/quickstart.html#install">installation instructions</a> detailed on the project
Web site. Also, read the <a class="reference external" href="https://pythonhosted.org/django-jython/database-backends.html">database backends</a> documentation there.</p>

<p id="index-1">At this point, Django on Jython should behave nearly identically to Django
running on standard Python. However, are a few differences to keep in mind:</p>
<ul class="simple">
<li>Remember to use the <tt class="docutils literal"><span class="pre">jython</span></tt> command instead of <tt class="docutils literal"><span class="pre">python</span></tt>. The
documentation uses <tt class="docutils literal"><span class="pre">python</span></tt> for consistency, but if you&#8217;re using Jython
you&#8217;ll want to mentally replace <tt class="docutils literal"><span class="pre">python</span></tt> with <tt class="docutils literal"><span class="pre">jython</span></tt> every time it
occurs.</li>
<li>Similarly, you&#8217;ll need to use the <tt class="docutils literal"><span class="pre">JYTHONPATH</span></tt> environment variable
instead of <tt class="docutils literal"><span class="pre">PYTHONPATH</span></tt>.</li>
<li>Any part of Django that requires <a class="reference external" href="http://pillow.readthedocs.org/en/latest/">Pillow</a> will not work.</li>
</ul>
